How to Finance a Custom Home: Construction Loan Options, Step by Step
Editorial review: My Construction Path team ·
Most people finance a custom home with a construction loan that pays the builder in stages, then becomes a regular mortgage. The main choices are a one-time close, a two-time close, a loan that also buys the land, land you own as equity, or cash now and a mortgage later. Lenders review you, your builder and your plans.

What are the best ways to finance a custom home?
The best option is the one that fits your land, your cash and how much paperwork you want. Here is how the common paths compare.
| Option | How it works | Often fits when |
|---|---|---|
| One-time close | One loan and one closing cover the build and the permanent mortgage | You will live in the home and want a single approval |
| Two-time close | A short construction loan, then a separate mortgage when the home is done | You want to shop the permanent mortgage later, or your project doesn't fit a one-time program |
| Land and construction in one loan | The loan buys the lot and funds the build | You have found land but haven't bought it yet |
| Land equity | Land you already own counts toward your contribution | You own the lot, with or without a balance left on it |
| Cash, then a mortgage | You fund the build yourself and borrow after completion | You have substantial liquid assets and want fewer lender rules during the build |
For the closing structures, see one-time close vs. two-time close. If you are still shopping for a lot, read whether you can buy land and build with one loan. If you already own one, see how land equity works.
How do you get a loan to build a custom home, step by step?
You move through eight steps, and the lender checks most of them before closing. Doing them in order keeps the file from stalling.
- Set a total budget. Add the lot, the builder's price, site work such as a well, septic or driveway, permits, design fees and a contingency. Our contingency calculator can help size that cushion, and the construction loan calculator gives a rough borrowing range.
- Secure the land. Buy it, put it under contract, or confirm clear title to land you own. Check access, utilities and flood zone early.
- Choose a builder. Ask each lender what it needs for builder approval before you sign or pay a deposit.
- Finish plans and a contract. Lenders and appraisers work from full plans, a specification list and a line-item budget.
- Pick a loan type. Conventional, FHA, VA, USDA and jumbo programs each have their own rules. Our guide on how to choose a construction lender covers what to compare.
- Get the appraisal. The appraiser values the home "as completed," based on your plans. See how a construction loan appraisal works.
- Close and draw. After closing, the lender releases money in stages as an inspector confirms work. See how construction loan draws work.
- Convert to a mortgage. When the home is finished and passes a final inspection, the loan becomes your permanent mortgage. See how conversion works.
On a one-time close, the lender controls the money during the build. Fannie Mae's Selling Guide on single-closing transactions says:
"When a single-closing transaction is used, the lender will be responsible for managing the disbursement of the loan proceeds to the builder, contractor, or other authorized suppliers."
The same section explains that "the construction loan will automatically convert to a permanent long-term mortgage loan upon completion of the construction."
Can you finance a home built by a custom builder?
Most construction lenders finance homes built by custom builders, but they approve the builder first. Expect the lender to review the builder's license where one is required, insurance, references, finances and the signed contract.
The U.S. Census Bureau defines this kind of project as a contractor-built house, one "built for owner occupancy on the owner's land with construction under the supervision of a single general contractor." As of the 2025 annual data, published July 1, 2026, about 130,000 contractor-built single-family homes were completed in the U.S. (Census Characteristics of New Housing).
To keep approval moving:
- Send the builder the lender's packet on day one.
- Use a fixed-price contract that includes everything needed for a certificate of occupancy.
- Make your contract contingent on financing and builder approval.
- If you are still choosing, our builder resources explain what to look for.
If the review stalls, see what to do when your builder isn't approved yet. Large deposits need extra care, so read how a builder deposit affects your construction loan before you pay one.
How long does it take to build a custom home?
Plan for most of a year once construction starts. As of the Census Bureau's 2025 annual data, published July 1, 2026, contractor-built homes took an average of 10.5 months from start to completion, compared with 6.1 months for homes built for sale (Census start-to-completion table).
That figure does not include design, permitting and loan approval, which come first. Our build time calculator can help you map your own schedule.
How much cash will you need?
That depends on the program, your land and your budget. Many lenders let land you own count toward your contribution, and some programs offer a low down payment option for eligible borrowers. See how much you need down to build a custom home.

Frequently asked questions
How do I get a loan to build a custom home?
Set a budget, secure the lot, choose a builder, finish plans and a contract, then apply for a construction loan. The lender approves you, your builder and an as-completed appraisal before closing.
Can I get financing for a house built by a custom home builder?
Yes. Most construction lenders finance custom builders, as long as the builder passes the lender's review and signs a contract with plans, specs and a line-item budget.
What is the best way to finance building a custom home?
It depends on your land, cash and timeline. A one-time close suits many owner-occupants. Land equity, a two-time close or cash plus a later mortgage can fit other situations.
Do I need to own land before I apply?
No. Some loans pay for the lot and the build together. If you already own the lot, its value may count toward your contribution.
